Simultaneous quantitation of two orchid viruses, cymbidium mosaic potexvirus (CymMV) and odontoglossum ringspot tobamovirus (ORSV), were carried out using the TaqMan((R)) real-time RT-PCR, a novel detection technique that combines RT-PCR with the power of fluorescent detection. Four TaqMan((R)) probes were synthesized, targeting at the RNA-dependent RNA(More)
Quartz crystal microbalance (QCM) immunosensors are based on the principle that adsorption of substances on the surface of a quartz crystal changes its resonance oscillation frequency. A QCM immunosensor was developed for the detection of both cymbidium mosaic potexvirus (CymMV) and odontoglossum ringspot tobamovirus (ORSV) by pre-coating the QCMs with(More)
A total of 15590 unique zebrafish EST clusters from two cDNA libraries have been identified. Most significantly, only 22% (3437) of the 15590 unique clusters matched 2805 (of 15200) clusters in the Danio rerio UniGene database, indicating that our EST set is complementary to the existing ESTs in the public database and will be invaluable in assisting the(More)
ABSTRACT Immuno-capillary zone electrophoresis (I-CZE) is a technique that combines the specificity afforded by serological assays with the sensitivity, rapidity, and automation in detection provided by capillary zone electrophoresis. Cymbidium mosaic potexvirus (CymMV) and odontoglossum ringspot tobamovirus (ORSV) were detected in their purified forms as(More)
ABSTRACT Molecular beacons are single-stranded nucleic acid molecules with a stem-loop conformation. The stem portion consists of complementary sequences at the 5' and 3' terminals of the molecule, while the loop portion consists of probe sequences that are complementary to the target sequences of choice. A fluorescent moiety is attached to one end, while a(More)
ABSTRACT We have developed a piezoelectric DNA-sensor based on DNA-RNA hybridization for the detection of two orchid viruses, Cymbidium mosaic virus (CymMV) and Odontoglossum ringspot virus (ORSV). Specific oligonucleotide probes modified with a mercaptohexyl group at the 5'-phosphate end were directly immobilized onto 10-MHz AT-cut quartz crystal(More)
